Tron 7.0 Dnamic Helicopter Kit (w/o Blades) - Yellow

Love flying this heli on 7S at 1550 head speed. 8 min flights and just an overall smooth heli. This has become my go to heli and the big blades and light weight is very forgiving for trying new things.

There are some real niggles with this model and some real positives too.
On the positive side this is a light model and well thought out from a mechanical point of view. It is not a 700 sized model - more of a stretched 580 size model. The head is quite small and not in the same class size of 700 machines at all. Sitting beside my Logo 550, it is just longer (i.e. stretched) and most definitely has 550/580 sized mechanics. This stretched model means that it is tail heavy even with a 740 gram, 6S battery fully forward.
Although the advertising literature specifically notes that cable/wire runs are thought out, this is not the case at all. Because of the frame size and minimalist approach, running servo wires, ESC and power wires, even utilizing a battery backup/buffer is not clean or easy. There is not much room to plan your routing and no provision for wire ties or cable run access through the frames. All the parts are preassembled: I understand why this is done, but there are several parts that are unnoticeable as preassembled units. One part are the aft canopy stays that utilize the quick latches - the posts are screwed together but this is not obvious and mine vibrated out. Also, the battery tray latch has a top piece (the button) that is not obviously screwed together at all. So yes, it vibrated apart in one flight and got lost. That's why they are backordered. Another aspect of poor implementation is the manual. There is no manual: Okay, that's kind of a thing now though SAB has great paper manuals in the kit. However, the online manual is poorly written, has low quality pictures, poor drawings, and none of the links in the document work (these links are to pages supplying supplemental information). Lastly, the skids included in the kit are for the actual 700 model and are much too long for the Dnamic which is really a 550/580 model. I ordered a replacement set, and these too are for the 700 - obviously a packaging issue there at the manufacturers site. It's actually a nice model, but for the same money, you can buy an SAB with main and tail blades for not much more, have excellent manuals, all the parts and clarity on what is screwed together needing thread lock and what doesn't. I'm reasonably happy with the model, but there are many improvements to be made for the money. It's worth noting that the manual mentions 3 individuals responsible for its development - one of whom was tied to Synergy. This brings to mind the whole Synergy helicopter debacle and Matt Boots loss of business. Who really knows the score there? Not a bad model, but worth looking at other options.
